Cardiovascular Physiology - Part 3

The cardiovascular system is composed of the heart and blood vessels. The basic function of the heart is to pump blood through the blood vessels. The basic function of the blood vessels is to serve as conduits to carry blood away from the heart to the tissues, and to return blood from the tissues back to heart. Test your basic knowledge of cardiovascular physiology by taking this simple quiz.

(1) This famous physiologist discovered the circulation of blood:

	(A) Ernest Starling
	(B) William Harvey
	(C) Marcello Malpighi
	(D) Andreas Vesalius
	(E) John Hunter

(2) This one-way valve separates the right ventricle from the pulmonary artery:

(3) Within the cardiovascular system, the highest hydrostatic blood pressure is found in the:

	(A) Left ventricle during ventricular systole
	(B) Left ventricle during ventricular diastole
	(C) Left ventricle during atrial systole
	(D) Left ventricle during atrial diastole
	(E) Aorta during ventricular systole

(4) Pacemaker potentials of the heart result from:

	(A) Na⁺ influx
	(B) K⁺ influx
	(C) Opening of I_f channels
	(D) Cl⁻ influx
	(E) Na⁺ efflux

(5) The plateau phase of the cardiac action potential is due to the:

	(A) opening of voltage-gated Ca²⁺ channels
	(B) opening of fast voltage-gated Na⁺ channels
	(C) opening of voltage-gated K⁺ channels
